SPINDLRFOR SPINNING OR TWISTING MACHINES A Z/f/ MVAV///// Patented Aug. 4, 1931 UNITED STATES FRED K. HENDRICKSON, 0F WORCESTER,

MASSACHUSETTS, ASSIGNOR TO WHITIN MACHINE WORKS, 015 WHITINSVILLE, MASSACHUSETTS, A CORPORATION OF MAS- SACHUSETTS SPINDLE FOR SPINNING OR TWISTING MACHINES Application filed November 2, 19 2 9 This invention relates to a spindle suitable for use in a spinning or twisting machine.

It is the general object of my invention to provide a spindle which is particularly adapted to heavy duty and which is very economical in power consumption. To this end my invention contemplates a novel ap plication of an anti-friction bearing to a heavy duty type of spindle.

My invention further relates to certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing which is a sectional side elevation of my improved spindle.

Referring to the drawing, I have indicated a spindle rail 10 forming a usual part of a spinning or twisting machine. A spindle base 12 is mounted in an opening in the rail 10 and has a threaded portion 14 extending down through the opening to receive a clamping nut 15. The usual spindle bolster 20 is slidably mounted in the spindle base 12 and is held from rotation by a wire key 22. Both the spindle base 12 and the bolster 20 project upward substantially above the spindle rail 10, as clearly shown in the drawing.

A spindle blade 25 has a bearing in the upper portion of the bolster 20, and the tapering lower end of the blade 25 has a step bearing in the lower end of the bolster 20 as indicated at 27 The blade 25 commonly has a clearance of .003 to .005 in the upper bolster hearing.

A driving whirl 30 is secured to the blade 25 and is provided with a depending flange portion 82 forming a driving pulley and enclosing the upper end portions of the spindle base 12 and bolster 20.

An oil-retaining cup 34 is mounted on the upper end of the spindle base 12, and a cooperating inverted cup 36 is mounted on the blade 25, within the cup 34.

A11 anti-friction or ball bearing is interposed between the depending flange 32 of Serial No. 404,478.

the whirl and the upwardly projecting portion of the spindle base 12.

The inner ball race 40 of the anti-friction bearing is mounted on the upper portion of the spindle base 12 and is retained in position by the oil cup 84. The flange 32 is recessed to receive the outer ball race 42 which 'is held in position therein by a bushing 43 and a spring locking ring 44.

An annular fiat spring ring 46 is mounted on the inner ball race 40 and effectively closes the opening between the inner and outer ball races, thus excluding dirt from the anti-friction bearing and from the space within and above said bearing.

In this type of spindle a relatively heavy transverse belt pull is applied to the de pending flange 32 of the whirl 30. This transverse pull is taken directly by the anti-friction bearing, which is so positioned as to most effectively resist this transverse or lateral'pull. I thus effectively avoid the tendency otherwise present to displace the blade 25 laterally or to cause the same to bind in the bushing.

In my improved spindle, it will be apparent that the usual bolster bearing retains its normal function of steadying the spindle blade and absorbing slight vibrations thereof, while the anti-friction bearing takes the substantial transverse pull of the belt.

Each bearing thus performs its separatefunction while the joint result thereof is a particularly satisfactory and easy running spindle of low power consumption.

Havingthus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims but what I claim is 1. A spindle comprising a spindle base, a bolster mounted therein, a blade rotatable in said bolster, a whirl mounted on said blade-and having a depending driving flange enclosing the upper end portions of said spindle base and bolster, and bearing means interposed between said depending flange and the upper portion of said spindle base.

2. A spindle comprising a splndle base,

a bolster mounted therein, a blade rotatable V in said bolster, a whirl mounted on said blade and having a depending driving flange enclosing the upper end portions of said 5 spindle base and bolster, and an anti-friction bearing interposed between said depending flange and the upper portion of said spindle base.

3. A spindle comprising a spindle base, 0 a bolster mounted therein, a blade rotatable in said bolster, a whirl mounted on said blade and having a depending driving flange enclosing the upper end portions of said spindle base and bolster, and an anti- 15 friction bearing having one race mounted within said whirl and having a second race mounted on the upper portion of said spindle base. i

4. A spindle comprising a spindle base, a bolster mounted therein, a blade rotatable in said bolster, a whirl mounted on said blade and having a depending driving flange enclosing the upper end portions of said spindle base and bolster, and an anti-- friction bearing interposed between said depending flange and the upper portion of said spindle base, said bearing being releasable from said depending flange.

5.- A spindle comprising a spindle base,

{Q- a bolster mounted therein, a blade rotatable in said bolster, a whirl mounted on said blade and having a depending driving flange enclosing the upper end portions of said spindle base and bolster, an anti-fric- 3- tion bearing interposed between said do,-

pending flange and the upper portion of said spindle base, and means to releasably secure said bearing in said depending'flan e. 6. A spindle comprising a spindle base, a

bolster mounted therein, a blade'rotatable in said bolster. a whirl mounted on said blade and having a depending driving flangeenclosing the upper end portions of said spindle base and bolster, an anti-friction bearin interposed between said depending flange and the upper portion of saidspindle base, and means to exclude dirt from the space within and above said bearing.

93 7. A spindle comprising a spindle base, a

bolster mounted therein, a blade rotatable in said bolster, a whirl mounted on said blade and having a depending driving flange enclosing the upper end portions of said spindle base and bolster an mti-frio tion bearing interposed between said depending flange and the upper portion of said spindle base, and an annular flat spring ring mounted on. a portion of saidanti-fric- QLtion bearing and effective to exclude dirt from the space within and above said bearm V in testimony whereof I have hereunto aflixed my signature.
